What is uplink referred to as?

• A. Used to describe the frequency transmitted to the satellite
• B. Used to describe the frequency received from the satellite
• C. Used to describe line-of-sight bandwidth
• D. Used to describe encryption key

Answer: (A)

In satellite communications, uplink is about the path and frequency used when sending signals from Earth up to the satellite. It describes the frequency you transmit toward the satellite, not what you receive from it. The signal that the satellite then retransmits back to Earth is the downlink. So uplink is the transmit frequency to the satellite, while the other options refer to things that aren’t about the direction or path of the signal (such as what you receive from the satellite or unrelated concepts like line-of-sight bandwidth or encryption keys).
